Systems and methods for orthogonal intraventricular access

Abstract

Devices and methods for stereotactic placement of a catheter are disclosed herein. The device can include a conical component comprising a first opening and a second opening, a cylindrical rod for receiving the catheter, a footplate for securing the device underneath a skin of a subject, and a clip for holding the catheter. The first opening and second opening can form a lumen therethrough. The cylindrical rod can be coupled to the first opening, and the footplate can be coupled to the conical component.

What is claimed is: 
     
         1 . A device for stereotactic placement of a catheter comprising:
 a conical component comprising a first opening and a second opening, where the first opening and second opening form a lumen therethrough;   a cylindrical rod, coupled to the conical component, for receiving the catheter;   a footplate, coupled to the conical component, for securing the device underneath of a skin of a subject; and   a clip, coupled to the conical component, for holding the catheter.   
     
     
         2 . The device of  claim 1 , wherein the second opening is located at a base of the conical component, wherein the base is configured to contact with a target tissue. 
     
     
         3 . The device of  claim 2 , wherein the target tissue is a calvarial surface anterior to a burr hole. 
     
     
         4 . The device of  claim 1 , wherein a diameter of the second opening is from about 0.5 cm to about 1.5 cm. 
     
     
         5 . The device of  claim 1 , wherein the conical component is a 180-degree hollow truncated conical component. 
     
     
         6 . The device of  claim 1 , wherein the first opening is located at a top of the conical component, wherein a diameter of the first opening is from about 0.25 cm to about 0.75 cm. 
     
     
         7 . The device of  claim 1 , wherein a height of the conical component is about 1 cm. 
     
     
         8 . The device of  claim 3 , wherein the device is configured to be placed on the calvarial surface anterior to a burr hole in a semi-circular way so that an entire burrhole is free for catheter placement. 
     
     
         9 . The device of  claim 1 , wherein the footplate is configured to be located at a calvarial surface anterior to a burr hole to secure the device underneath a skin of a subject. 
     
     
         10 . The device of  claim 9 , wherein a length of the footplate is from about 0.1 cm to about 2 cm. 
     
     
         11 . The device of  claim 9 , wherein a portion of the cylindrical rod is located in the lumen. 
     
     
         12 . The device of  claim 1 , wherein a diameter of the cylindrical rod is from about 0.1 cm to about 0.75 cm. 
     
     
         13 . The device of  claim 1 , wherein the cylindrical comprises a lumen that is configured to receive a catheter so that the catheter is aligned parallel to the cylindrical rod and placed through a frustum of the conical component into a ventricle. 
     
     
         14 . The device of  claim 1 , wherein the clip is configured to hold a catheter in place during a surgical procedure. 
     
     
         15 . A method for placing a catheter comprising:
 placing a device on a target hole for inserting the catheter, wherein the device comprises
 a conical component comprising a first opening and a second opening, where the first opening and second opening form a lumen therethrough; 
 a cylindrical rod, coupled to the first opening, for receiving the catheter; 
 a footplate, coupled to the conical component, for securing the device underneath of a skin of a subject; and 
 a clip, coupled to the conical component, for holding the catheter; 
   aligning the catheter parallel to the cylindrical rod; and   placing the catheter through a frustum of the conical component into a target tissue.   
     
     
         16 . The method of  claim 15 , further comprising holding the catheter using the clip during a surgical procedure. 
     
     
         17 . The method of  claim 16 , wherein the device is printed using a three-dimensional printer. 
     
     
         18 . The method of  claim 15 , wherein the subject shows an indication, wherein the indication comprises subarachnoid hemorrhage, intraventricular hemorrhage, traumatic brain injury (TBI), hydrocephalus, pseudotumor and post-surgical wound drainage, or a combination thereof.
